    to a leaching process. When fine grinding pyritic concentrates of precious metals, it is common to follow the fine grinding stage with a pre-aeration stage to remove active pyrite and pyrrhotite before cyanidation. Worn steel media in the ground pyrite can significantly increase the pre-aeration time needed.Mining equipment for Pyrite processing,The specific gravity of pyrite is higher and the specific gravity of gangue is lower. Through crushing and grinding, intergrowth structure in pyrite will be destroyed. The pyrite ores areput into jaw crusher for the primary crushing. Then, the ores will come into storage bin when they are crushed to a reasonable fineness.
